SPECIFICATION'forming part of Letters Patent No. 293,604, dated February12, 1884.

To all whom it may concern:

Be it known that we, MERRILL A. TYLER and DANIEL S. SMITH, of Rockland,in the county of Plymouth and State of Massachusetts, have inventedcertain Improvements iii-Machines for Finishing Heel-Bottoms, of whichthe following is a specification.

This invention hasfor its object to provide an improved machine forfinishing the bottoms of boot and shoe heels by filing and sandpaperingthe same; and it consists, as a whole, in an organized machine embodyinga metallic cylinder-file and a roll coated with sandpaper or otherabrasive material, said rolls [5 being mounted on the same arbor, andadapted to operate on 'the bottom of a heel presented by the operatorsuccessively to the cylinder-file and the sand-paper roll, there beingrests or bearing-surfaces on either side of the cylinder-file, saidsurfaces being adjustable,

both as to the angleat which they stand relatively to a given horizontalplane and as to- 3 5 in section. Fig. 5 represents an enlarged end viewof thecylinder-file and adjustable heelsupports. Fig. 6 represents asection online as 00, Fig. 5. Fig. 7 represents a view of thecylinder-file detached. I The same letters of reference indicate thesame parts in all the figures.

In the drawings, A represents a suitable supporting-standard, havingbearings for a horizontal arbor, B, which has a pulley, O, belted v 5 toa pulley on a driving-shaft, D.

To one end of the arborB is secured a metallic cylinder or roll, E,having its periphery corrugated, grooved, or indented, to formfile-teeth, which may be produced by groova leather surface.

ing the cylinder diagonally in two directions, 5o

as shown in Fig. 7, or by any of the methods used for forming file-teethadapted to cut away To the opposite end of the arbor B is attached aroll, F, coated with sandpaper or other abrasive material adapted tobuff a leather surface.

"Over the rolls E F are hoods G G, connected by trunks H H with thecasing J of an exhaust-fan, I, which is rotated by a belt-connectionwith the driving'shaft, and removes the powdered leather produced by theaction The frame A has a vertical fiange, K, close to the inner end ofthe cylinder-file E, the arbor B passing through an aperture, L, in thesaid flange, as shown in Fig. 6. I

To the flange K is secured by screw-bolts M M a flat plate, N, having anannular boss, 0, through which the arbor B passes, said boss having anaperture, P, considerably larger than the arbor, so that the plate N canbe raised and lowered independently of the arbor, the plate beingprovided with vertical slots B B, through which the bolts M M pass, thatsecure the plate N to the flange K.

S represents a hood or casing formed on a plate. T, which is fitted tothe boss 0, and is secured to the plate N by bolts U U, passing throughcurved slots U U in the plate T, said slots enabling the hood S to bepartially ro- 8o tated on the boss 0 when the bolts U U are loosened.The hood Spartially surrounds the cylinder-file, and is of aboutthe samelength as the latter. In the lower portion of the hood S is an opening,which permits the lower portion of the periphery of the cylinder-file toproject from said hood. On the opposite sides of said opening plates V Vare affixed to the hood S by screws W W, passing through transverseslots a a in the plates V, whereby said plates are made adjustable tovary the width of the opening through which the cylinder'file projects.The plates V V are in line with each other, and constitute rests for thebottom of a heel at opposite sides of the cylinder-file. The

hood S is so adjusted that the plates or restsV V will stand diagonally,their inclination being upward from the rear to the front of themachine, this being found to be the 1nostconvenient position.

In operating on a boot or shoe with this machine, the operator pressesthe bottom of the heel on the rests V V, thereby subjecting the heel tothe action of the cylinder-file, which quickly removes all theprotuberances on the bottom of the heel and reduces it to a fiateondition, also rasping off the ends of the nails, if any there be.After the heel has been sufficiently rasped or reduced by thecylinder-file, it is subjected to the action of the roll F,whieh impartsa smoother surface than that left by the cylindeniile. The verticaladjustability of the hood S (allowed by the slots R R and 1 in the plateN) enables the degree of projection of the cylinder-file from the hood Sto be regulated so as to make said file cut more or less deeply into theheel. The adaptability of the hood S to be partially rotated enables theinclination of the rests V V to be regulated to suit differentoperators. The lateral adjustability of the rests V V enables the spacebe tween them to be varied to suit differentsizes of heels. The hoods GG are pivoted at b I) to the ends of the trunks H H, so that they canbereadily raised to expose thehood S and the roll F.

If desired, our improved machine may be used for the bottoms of soles aswell as heels.

\Vhen the file is intended for use on the shank portion of the sole, therests V V should be removed and the file allowed to project from itseasing S to a greater extent than is shown in the drawings, so that theconcave portion of the shank can be presented to the file withoutobstruction by the rests.

A jack, J may be employed to support the boot or shoe while the bottomof theheel is being presented to the file, as shown in Fig. 3. 0

The jack is adjustably secured by a clamp, J to a standard, J so thatthe boot or shoe can be inclined to correspond with the inclination ofthe rests V V. The standard J is pivotally connected to a pedal-lever,J", which is pivoted to the standard A. The operator is thus enabled tooscillate the jack and present to the tile all parts of the surface "tobe operated on thereby.

Ve clailn- 1. The combination of the cylinder-file and the rests V V, asset forth.

2. The combination, with the cylinder-file, of the adjustable restsV V,substantially as described, and for the purpose stated.

The combination, with the cylinder-file, of the adjustable rests V V,the hood S, to which said rests are secured, the slotted plate N, andthe flange K, the parts being held and adjusted by setscrews, and allbeing arranged substantially as described.

4-. The combination, in an organized machine, of a rotary cylinder-file,the guardplates arranged to gage the depth of cut of said file, andashoe-holdingjaek pivoted toastandard, as described, so as to presentthe heel properly to said file, substantially as shown and described.
